Mayor Vince Gray bet big on the ‘Skins game yesterday against the Seattle Seahawks, and now D.C. is going to have to pay up. Gray, in a playoff gamble with Seattle Mayor Mike McGinn, wagered that if the ‘Skins had prevailed, a D.C. banner reading “Taxation Without Representation” would fly above Seattle City Hall for a weekday.

But the ‘Skins lost, 24-14, and to make good on Gray’s bet with McGinn, it is the District that will be swapping out its flag for that of Seattle’s. The city’s current flag was introduced in 1990, and features a stylized portrait in white of Chief Seattle—the 19th-century Duwamish chieftain and environmentalist for whom the city is named—against a teal background. It also features one of Seattle’s mottos, “City of Goodwill,” which was adopted along with the flag when the city hosted the 1990 Goodwill Games.

Pedro Ribeiro, a spokesman for Gray, says the Seattle flag will be raised at the John A. Wilson Building “when they send” it.

In the mean time, for a primer on our newfound status as Seattleites—or is it Seattleans or Seattlests (too soon)?—The Washington Post devoted some space last weekend to comparing our Washington and their Washington. Basically, the Post found that people in Seattle are cooler than you:

Rep. Jim McDermott (D), who has represented his Seattle district in Congress since 1989, says his weekend Washington is much more relaxed than his Monday-Thursday Washington. Coats and business attire are still required in far too many D.C. settings, he said. And people charge from meeting to meeting “like they are running with the bulls,” often against the crossing light.

Hail, hail, hail to our new laid-back overlords.
